Peanut Ball in Labor to Reduce Anxiety and Pain

An open clinical trial-type study of randomized assignment groups, an interventional model of parallel assignment, will be carried out to establish whether or not there are significant differences in the levels of anxiety and intensity of pain, in labor in patients who use the peanut ball and those that don't.

About this study

The process of labor is a unique and significant experience in a woman's life, and obstetric care is constantly seeking strategies to effectively improve the experience of this crucial event.

Now in response to the growing global attention to quality and respect in maternity care, the International Childbirth Initiative (ICI) has outlined "12 steps to safe and respectful maternity care, which advocate for safe and respectful maternity care".

The declaration of rights of the World Health Organization (WHO) in the year 2021 highlights the urgency of "acting now for a safe and respectful childbirth", reinforcing the global commitment to respect, protect and fulfill the right to health, particularly maternal health. In this context, it emphasizes the need to ensure a positive, satisfactory and well-being experience during pregnancy and childbirth, in Honduras is part of this group of initiatives in order to promote an environment of respect for the mother at the time of childbirth.

Most healthy women can give birth with a minimum of medical procedures without putting at risk the mother-child binomial, the safest delivery is the one that evolves spontaneously and in which there is no unnecessary intervention, for that is necessary health facilities that have the requirements to provide delivery care and professionals who understand what are the basic needs of women during this physiological process. For decades, peanut balls have been used as a non-pharmacological complement for labor management. So far, this non-drug strategy has shown significant advantages in several aspects, among them, pain control, anxiety reduction, improvement in maternal experience and positive influence on obstetric indicators.

In the national and international context of guidelines and commitments towards safe and respectful maternal care, there is a need for a localized and specific evaluation of interventions, such as the use of the peanut balloon, to understand its efficacy in reducing anxiety and pain during labor, With the development of this study we aim to evaluate the efficacy of the use of the peanut balloon as a therapeutic intervention to reduce anxiety and pain in women during labor at Hospital Escuela Universitario in the period from June 2024 to June 2025, which could contribute to the knowledge about therapeutic practices in the obstetric context, providing solid scientific evidence on the efficacy of the use of the peanut balloon. The successful implementation of this intervention could have a positive impact on both women's experience and obstetric clinical practice, and is expected to serve to establish a protocol for the management of labor and delivery using the peanut ball.

Treatment and study plan

Peanut Ball

Device

Participants will be provided with a mani ball, which will be covered by a cover provided by the investigator. This cover will be changed for each patient. The ball will be placed between the participant's knees, and she will be allowed to use it at least every two hours for a period of 30 minutes. Participants will also have the option to use the balloon more frequently if they wish. Balloon use will be discontinued when the cervical os reaches 10 cm dilation or when the participant is ready to begin the pushing process.

  • The positions to be performed with the peanut ball will be:
  • Side lying
  • Bent position
  • Semi-sitting position
  • Taylor position.

Other names: peanut shaped ball, peanut labor ball

Primary outcomes

  1. anxiety level

    Time frame: Since intervention until 8 hours

    Pain Anxiety Symptom Scale - Short Format 20 (PASS-20), This test measures 20 items using a Likert scale from 1 to 5, with a minimum score of 20 and a maximum of 100.

  2. Visual Analog Pain Scale

    Time frame: Since intervention until 24 hours

    It is a horizontal line of 10 centimeters, at the ends of which the extreme expressions of a symptom are shown. On the left side is located the absence or lower intensity and on the right side the higher intensity. The patient is then asked to mark on the line the point indicating the intensity and it is measured with a millimeter ruler. The intensity is expressed in centimeters or millimeters

Secondary outcomes

  1. Maternal Well-being in Childbirth Scale 2 (BMSP2)

    Time frame: Since intervention until 24 hours

    The total scale score defines three levels of maternal well-being: excellent (score > 200), adequate (score > 183 and <. 200), and poor (score < 183), the score range has a minimum of 47 and a maximum of 235

  2. The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ)

    Time frame: Since intervention until 24 hours

    measures the Fear of childbirth. It is divided into 2 parts, part A with 32 items with a Likert scale (32 to 192 points) and part B with 30 points with a Likert scale (30 to 180 points)
